Release Regression From : 1.4.2_04
The above release value was the last known release where this 
bug was known to work. Since then there has been a regression.

(Incident Review ID: 286707) 
======================================================================

N/A

The behavior change was made due to the same ClassLoader change in 1.4.2_05 as in Tiger. Please refer to http://java.sun.com/j2se/1.5.0/compatibility.html#incompatibilities for details.

Please note that '/' isn't the correct separator for a qualified class name. '/' is allowed in getBundle only for PropertyResourceBundle for JDK 1.1. compatibility.

Reopening the bug as the bug is escalated for 1.4.2_05. Issue is compatibility
with previous versions of 1.4.2x. 
Will keep this bug open until the Cu's issue is resolved.
